A male in heaven could be granted many houris, besides one primary wife. Though in Jannah, a woman would only desire one male companion. Though for a woman that was unmarried in this life, and granted Jannah she becomes married to a male companion. What is the name of this kind of creature? I know it’s not a "houri" or "male houri", as that is primarily female.

Probably al-Wildan al Mukhaladoon
